Show abstract
We present here four biomedical, multi-entity corpora that can be used as benchmarks for named-entity recognition (NER), targeted to literature on metabolic syndrome. The CoDiet-Gold corpus (348,413 annotations) contains 500 re-distributable full-text publications, of which each document was independently annotated by two human experts, with disagreements fully adjudicated by a third expert. The CoDiet-Electrum corpus (2,349,499 annotations) contains 3,688 publications that were annotated using the entities from CoDiet-gold. Finally, for the same 3,688 documents, two fully machine-annotated corpora CoDiet-Bronze (2,399,647 annotations) and CoDiet-Silver (1,868,422 annotations), were created by utilising existing NER algorithms to annotate these. These corpora contain categories (organisms, disease, genes, proteins, metabolites) that add depth to existing corpora, as well as new categories that do not have other corpora (food, dietary methods, sample types, computational methods, study methodology, population characteristics, data types, and microbiome).
